Similar reference characters in the dierent figures of the drawingsindicate corresponding elements orfeatures of construction hereinreferred to.l

In practically carrying out the objects of the invention the socketportion thereof preferably' comprises a number of parts of v which onepart is formedas a. truncated tubel .composed of sheet metal, oneYen'd'of i the tube having an outwardly extending flange 2 thereon fromwhich extendsa skirt whichv may be variously shaped for orna- .mentalpurposes yand `preferably comprises a flaring portion 3 extending fromthe flange so as to encircle the tube, a cylindrical portion 4 extendingfrom the portion 3 4and from which a flaring portion 5 extends, acylindrical portion 6 .extending from the portion v5 to a plane beyondthe opposite end of tube l, the tube and the skirt preierably being spunfrom a single piece of metal, andthe end of the portion 6 prefer- A ablyis turned over to form a stiffening bead 7. Preferably the skirt orsocket cover is `formed of two layers so as to have double thickness ofmetal, 'that described being the inner portion or layer of the skirt,the outer portion or layerl thereof comprising a cylindricalportionS-.extending Vfrom the beadV about the portion 6 and vpreferablyformed integrally with the bead, a portion 9 correspondingjto theportion `5 extending from the portion 8, a portion 10 corresponding vtoportion 4 extending about the latter from the portion 9, a contractedportion ll extending from the portion 10 on to the portion 3, acontracted portion l2 extending yfrom the portion 11, an approximatelycy lindrical neck 13 extending -froin the portion 12,. the neckbeingfslightly larger .in diameter than the tube 1 and having screw'threads .lll formed on its end portion. The f exterior of the skirt andneck is approximately bell-shaped, and the neck has ,a slot l5.extending from the end or top vthereof when a switchl is usedadjacentto the socket, or maybe omitted when the lampislprovided with afswitch or circuit breaker at a considerabledistance from .the lamp.4,The inner and outerfportions of the's'kirt may be Slightly separatedduring formation as in Fig. 7 but 'are brought closely together whenfinished. Suitable devices are provided to 'in and receiving set-screws19, 20 and 21 re-4 spectively for' engaging the neck of the shade. Adome shaped .f crown 22 is pro vided, preferably of sheet metal, and itsedge lportion is provided y.with screw threads 23 adapted to screw on tothe threads 14, so as to not accidentallyfbecorne'disconnectedtherefrom, the crown partially covering the slot when in properposition.l The top or middle portion of the crown is provided with acol' lar 24 preferably having screw -threads 25 therein for connectionwith a' supporting pipe that comnionly-incloscs thecircuit wires portionvformed integrally 'withV one. end loffor the lamp, a set-screw 26preferably being Ainserted in the collar for securing the latter to thepipe.' Preferably the collar has Vsockets'27 and 28 in opposite portionsthereof in' order that the collar may be providedwith'a supporting ringor loop 29 that has l lugs 30 and 31 adapted to be 'inserted into thesockets, in case the collar is .not con- "nected to the pipe and it isdesired to suspend it by means of a chain or cord.

In 'accordance with common practice 'a' tubular. insulating lining 32 isplaced'within the-tubel and extends through it into the neck 13, theupper' portion of the lining preferably being slightly greater in diame'ter than that within. the tube and having a l bearing upon theangeportion 2. A switch' box or'plug 33-is placedwithin the neck porosed ofporcelain, and it has a socket memtion of'the lining and ma'ysuitably becomer 34 secured thereto that is providedwith screw threads 35 to whichthe electric lamp shank is directly connected, so as to forman electriccircuit therewith4 and. in connection with a contact'point 36 with whichthev switch box is provided as usual, a shaft 37 beingrotatably'mounte'din the switch box Y and having akey shank 38 thereon that ex- -f tends''through the slot 15 `and is provided on its;outer end with a handleorle'ver 39. The circuit wires 40 are brought through the collar 24 andconnected with 'suitable binding postsfinthe 'switch box that areconnected with a contact device 41 adapted to beenged by a' switch arm42 mounted on the shaft 37, the switch arm being moved into A contact'with a plate on'which the contact point 36 is formed to clo'se thecircuit, as will be understood. ,g'

When assembling the various elements of l'the invention'the circuitwires are passed through the collar 24 and properly connected 'with theswitch box, and the latter 'and the socket member 34 are inserted in theinsu-.j

latin vlining 32, after' which the liningV is insert' into the tube 1which constitutes a casin' for4 the insulation, the shank' or stem sis38 benigreadily movedv into' the slot 15 of 1 3 which constitutes acasingfor the switch box, after whic'hthe crownor cover 22 is screwedonto theneck or'otherwise detachably secured to the neck, as maybedesired.'v 4,

In practical use the electric lamp is 'screwed into the socket member 34as is customary, and the lamp shade 1s inserted into the' skirt or .ringthat extends 'about' the socket and is removably heldby the set-L screws19, 20 and 21. The circuit is'made or broken in the usual manner.
